POWER-TRANSMISSION MECHANISM,

Specification of Letters Patent.

Patented Fee. 24:,

Application filed March 30,1907. Serial No. 365,473.

To all who-m it may concern:

Be it known that I, WILLIAM L. BUCK, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Power Transmission Mechanism, of which the following is a full, clear, and exact description.

This invention relates primarily to means for varying the speed of a rotating shaft, and while adapted to be used in various connections it is especially designed for use with automobile and marine power transmission mechanism. v

The invention consists in the special construction and arrangement of the mechanism illustrated in the accompanying drawings, in which drawings like characters of reference indicate like parts throughout the views, and in which.

l igure 1 is a side elevation of a device embodying my invention; Fig. 2 is a plan view of the same; and Fig. 3 is a side elevation of a device showing a modified arrangement of the parts.

As'illustrated in the drawings, 1 represents a drive shaft connected with an auxiliary shaft 2 by means of a flexible joint 3. The

free end of the shaft? is journalcd in a bear ing box 4 which is monnted'to slide upon gui le-ways 5 attached at their ends to a bed plate 6 by means of bolts 7. The free end of the shaft 2 is provided with a friction wheel 8 having; a convex face 10 and a hub 9 fixedly attached to said shaft. An auxiliary wheel 11 is fixed to a shaft 12 which is journaled in standards 13 of a frame or yoke 14 pivotally mountedupon the bed plate 6 by means of a pivot pin 15. The auxiliary Wheel 11 is provided with a double beveled face, one side 16 of which is adapted to bear against the convex face of the Wheel 8, the opposite bevel 17 bearing against the beveled face 18 of a friction Wheel 19, preferably provided v'itli a hub 20 which is fixedly attached to a shaft 21 journaled in a pedestal 22 which, is

An arm I also mounted upon the bed plate 6. 24 is fixedly connected to the yoke 14 and pivotally attached by means of a pin 23'with a link or rod 25, "whiohmay be connected in any suitable vmanner with operating or adjusting mechanism so as to partially rotate the yoke 14 on its pivot and cause the faces creased as the outer portion of the "versely, the speed of the intermediate ivrr of the intermediate wheel to bear. firmly against the faces of the driving and driven. wheels.

in the construction shown in Figs. 1 and the driven shaft 21 is arranged horizontally Such arrangement of the parts may be modiiied, however, and the shaft inclined as shown in Fig. 3. Mechanism of any suitable construction may be connected with the pivoted shaft 2 to move said shaft laterally in its bearings and lock the shaft in anyiiesired position-on said guide Ways.

When the device is in'operation and the parts arranged as shown in Fig. 2, the shaft 2 transmits no motion to the auXili 7 or friction Wheel 11 and oppositely disposed friction wheel 19, for the reason that the beveled face 16 of the-auxiliary wheel is ar, ranged opposite the center of the face pf the friction wheel 8. When, however, the Wheel 8 is moved laterally with the free end bf the shaft, the rotary movement of the Wheel 8 is imparted by, frictional contact to the aux-- iliary Wheel 11, which in turn transmits s i if motion to the oppositely disposed f Wheel 19 and the. driven shaft 2i upon s. 5 said Wheel is mounted. The direc itm rotation of the auxiliary fri '3. andshaft 21. is varied or deteriri' side of the friction Wheel 8 Wi'iich against the beveled face 16 of the ar as Wheel 11. One side of said f rotates the auxiliary vvleel tion, and the opposite side tates said Wheel in the or the driven shaft 21 f0 of rotation of the Wheel. The sp'ed of 1 obviously varie i i the rela the face 16 of the intermediate on the face of the drive wheel the the auxiliary or intermediate wheel Wheel is brought in contact with the fr surface of the intermediate Wheel.

l is decreased as the central portion of the drive Wheel is-bmug'ht to bear age opposite face of the intermediate r The beveled faces of the intermediate are held firr y against the faces of ing and driven wheel by means of the crank-lever which rotates the yoke ii on pivotal supports, and enables all lost Infill-Lin said shaft and provided with a convex face,

a driven shaft. an oppositely disposed driven wheel mounted on said shaft and provided with a. beveled face, a yoke intermedlate said wheels, and a wheel provided with a v1. In a power transmission mechanism. 1

the combination of a pivot-ed shaft. a drive wheel mounted thereon and provided with a convex surface, a driven wheel having beveled face, and an intermediate wheel' provided with a double bevel arranged between said Wheels.

2. In a power transmission mechanism, the combination with a pivoted shaft, of a drive wheel mounted on said shaft and provided with a convex face, a driven shaft, a

Wheel mounted on said driven shaft and pro vided with a beveled face, a pivoted frame intermediate said wheels, and a wheel provided with a double bevel journaled in said frame.

In a power transmission mechanism, the combination with a pivoted shaft, of a bearing box for said shaft, curved guide ways adapted to seat said box, a drive wheel mounted on the free end of said shaft and provided with a convex face, a driven shaft, an oppositely disposed driven wheel mount-- ed on said shaft and provided with a beveled face, and an intern'iediate friction wheel provided with a double bevel engaging the faces of said wheels.

4. In a power transmission mechanism, the combination with a pivoted shaft, of arc guide ways, a bearing box adapted to reeeive said shaft and slide in said guide ways, a driven wheel mounted on the free end of t u l double bevel journaled on said yoke.

5. In a power transmission mechanism, the combination with a pivoted shaft, of

f curved guide ways, a bearing box for said shait'adapted to slide on said guide ways, a

drive wheel mounted on the free end of said shaft and provided with a convex face, a driven shaft, a wheel mounted on said driven shaft and provided with a beveled face, a pivot-ally mounted yoke, an intermediate friction wheel provided with a double bevel and iournaled on said yoke, and llzQiHlS for rotating said yoke on its pivotal support.

6. Ina power transnission niechanism, the combination of a drive shaft having a 5 laterally movable free end, a drive wheel I mounted on said shaft and provided with a convex face, a driven shaft, an oppositely disposed driven wheel mounted on said shaft and providedwith a beveled face, a vertically pivoted yoke, and an intermediate friction wheel mounted on said yoke and provided with oppositely disposed bevels bearing; against the drive wheel and driven wheel respectively.

In testnnony whereof 1 have signed my name to this specification in the presence of two subscribing witnesses.
